VALVE DEVICE.

This invention relates to valve devices and more particularly to flushvalves for toilet fixtures.

One object of the invention is to incorpoy Vvalve will not be unseatedin the closing of rthe main valve should the operating mechanism be heldin valve open position. V

Another' object of the invention is to have the actuating mechanism forthe auxiliary valve operable through the guide.v of the main valve andthus reduce the height of the valve device by having said actuatingmechanism closer to the main valve.

A further object of the invention is to provide the auxiliary valve onthe main valve with a spring mounting in vorder to insure proper andquick closingrof the auxiliary valve when released.

A further object of the invention is to so form the seat for theauxiliary valve on the main valve that the seat forming means provides aconvenient guide for the spring of the pressure reducer which isassociated with the main valve.

A further object of the invention is to incorporate the housing for thepacking of the timing pin directly in the valve housing so that thepacking assembly may be easily made at a reduced cost-of manufacture andwith a minimum number of parts.

A further object of the invention is to ieciprocably mount theVauxiliary valve'on the main valve and to provide a pivotally mountedlever on the main valve for actuating the' auxiliary valve through thevalve actuating' mechanism which iscarried bythe main housing of thedevice.

The invention consists further in the matters hereinafter described andclaimed.

A In the accompanying drawings@ I VF 1 is a vertical sectional viewthrough a valve device of our invention;

1921i. serial No. 284,132.

Fig. 2 is a side view of the guide to be hereinafter described;

F 3 is a top plan view of the same; and Fig. 4 illustrates the action ofthe depressible pin to be hereinafter described. Y The valve device -ofour invention comprisesV a main housing l'of cast brass or othersuitable material. The housing 1 is provided with a passage for the, owof liquids therethrough andsuch passage includes a chamber 2 within thehousing and inlet and outlet connections 3, 4 at the opposite ends ofthe passage witht-he inlet connection l3 in constant communication withsaid chamber. the outlet connection 4 by an upright cylinder 5 havingits lower end cast integral with the housing and opening into saidoutletconnection. Said cylinder extends upward though the chamber 2andhas its upper end forming a seat for the main valve 6 which .controlsthe flow of vliquids through the housing 1 from inlet 3 to outlet 4. Theconnections 3 and 4 may be threaded for attachment .to the source ofwater supply and toilet fixture, respectively.

The main valve is in the form of a pis- Vton valve fitting within acylindricchamber 7 provided in the housing 1 above the chamber 2 andforming an upward continuation thereof. The piston valve 6 has a slidingAfit in Vchamber 7 and divides the latter from chamber 2 in allpositions of the valve, whether open or closed. The valve 6 has asealing leatherS which engages the inner wall of the chamber? to seal itfrom chamber 2 in all positions of the valve.

The head of the piston valve 6 is formed by ,a metal plate or disc 6, tothe under side of which is secured a depending tubular guide 9 havinglongitudinally extending radial webs 10 which engage the inner Surfaceof the cylinder 5 to guide the piston 6 in its opening and closingmovements. `f The webs 10 are made long enough so as to hold the mainvalve 6 central in all positions of its movementand thus provide for asilent operating valve by preventing chattering or hammering.

The latter is divided fromrv The tubular guide 9 has screw-threaded Yand is held inplace by a metal cup-shaped retainer 12 so as ,to seatonthe upper edgev valve 15 has a stem 16 which extends down- CAD wardthrough the tubular projection 13 and into the guide 9 through a bearingspider 17 at the upper end of the guide. The spider holds the valvecentral and guides it in its openingand closing movements. By this formof structure anon-tilting reliei valve may be employed.

To close thevalve 15 and maintain it rtight against its seat whenclosed, we provide a coiled spring 18 about the stem'16 between thespider 17 and an arm 19 to which the lower end of the stem is connected.Said arm 19'is `one ot the arms ot' a lever 2O which is fulcrumed at 21on a lug 22 carried by the guide 9 at the upper end oi' a vertical slot23 in the cylindriewall of said guide, as shown in Fig. 2. rIhe spring1S presses down on the arm 19 and thusV closes the valve. The stem 16 isconnected to the arm 19 in any desired manner, as for example by havingan enlargement 24 on the lower end ot the stem beneath the arm 19 and areduced por'- tionV 25 of the stem extending through a suitableslot oropeningl in the arm.

A by-pass 26 is cored in a boss 1a on the housing '1 on the intake sideVof the `valve during the casting oit the housing. Said by-pass isenlarged where it opens into 'thi inlet connection 3 so as to allow tora free and uninterruptedilow elE `liquids into the passage. The wall 27et the housing on the rear side of the by-pass 26 extends downward intheliow through the connection 3 so as to provide a baille 'for directingliquids into the passage 26. A port or hole 2Sl is drilled through thewall 27 at the upper end oi" the passage 26 so as to provide acommunication between said passage and the chamber 7 'above the pistonvalve 6 and thus permit liquids to lill the. chamber 7 from the intakeside of thevalve. ,i

' The upper surface ot the piston Vvalve 6 as exposed to the waterpressure in the chainber 7 is greater in area than the under sui'- faceof the valve which is exposed to the water pressure in the chamber 2when the valve is closed. The result is that, although the pressure inthe chamber 7 will be the same as on the intakeside oi the valve, thevalve 6 would be held closed against its seat at the upper end Vot thecylinder 4 by reason of the larger area being exposed to the pressure inthe chamber 7.

Arranged in the chamber' 7 above the piston valve 6 is a coiled spring29 having its lower portion Ybearing against the plate 6'u1 about thetubularprojection 13. The upper end of the spring 29 bears against anadjusting nut 30 on a threaded stud 31 which extends into a recess 32provided in a cap or cover 33 screwed on or otherwise removablyconnected with the housing over the top of the chamber 7 Theupper end oithe stud 31 fits in a concave seat'32l in the recess 32 to hold the studfrom lateral displacement.

The nut 30 lits in said recess 32 and is held in adjusted position onthe stud by a locli nut 84.- The spring 29 has a tension lessthanthehydraulic pressure required to open the valve 6. The stud, nut,and recess assembly at the cover 33 and the tubular projection 13 at themain valve 6 provide a guide and support for the opposite ends of thespring 29 and hold it in central position.v VThe nut 30 is channeled orgrooved on its under side to receive the adjacent end of thevspring andhold it from displacenient with respect to the nut.

The spring assembly just described provides a pressure reducer withinthe housing 1 andv enables the pressure at which the liquids aredischarged past the valve 6 to beV reduced to the pressureA desired andthereby prevent Vsplashing and' violent action when the valve device isused with a high pressure system. By adjusting the nut 3() the tensionof the spring 29 may be regulated so as to reduce the pressureV at whichthe liquids are discharged frein the device to the low pressure desired-Thus the valve may be set to discharge the least amount ot liquids atthe lowest pressure desired and economically function without waste ofliquids or waste of pressure.

When equipping tall buildings, suoli as employed for offices, hotels,apartments, and the like, the Ypressures at which. the various valvesare desired vto operate may be set to accord with the pressureVconditions existing at different levels and thus provide for economicoperation of the valves and the amount o't' liquids employed in theflushing operation. 'In order that the water for the system for anentire building may reach the uppermost floors, it is necessary togenerate a considerable pressure in the system. This pressure isconsiderably higher at the lower floors than at the upper floors, and asa result our improved flush valves can be economically used because thepressure reducers incorporated therein can be set to compensate 'for theincreased pressures encountered at the lower floors. This enablesthevalve to operatev silently, quickly, positively, and economically at thedifferent pressures encountered on the different floors without llOviolent or agitated discharges from any valve and without subjectingthevalves to excessive wea-r or strain by reason of the higher pressures asencountered on the lower floors. f

The flow through port 28 is controlled by aV timing pin in the form ofaVscrew 35, which is mounted in the boss in alignment with the port 28.The head of the screw is accessible from the exterior of the. housing 1for adjustment by being located in a chamber 36 formed in the boss. .Thechamber is closed by a removable cap 37 to protect the The screw extendsthrough aV suitable packing 39 which is compressed between the inner endof ythe chamber 36 and the head of the screw, as shown in Fig. 1, so asto prevent leakage about the screw. The packing is so made that itconforms to the shape of the inner end of the chamber to make a tightjoint and is resilient enough to be compressed by the screw in alladjusted positions thereof. To compress the packing, the screw has apressure member 40 which' may be formed integral with the screw orconstitute a separate part in the form of' a washer as shown. Thisconstruction provides a simple form of packing and avoids the expensivehousing and packing arrangements as heretofore employed. Q

For operating the-auxiliary' valve 15 to relieve the pressure'in thechamber7 so that the mainA valve 6 may be opened by pressure on itsunder side, we provide a novel form of operating mechanism, as shown inFig. 1. This `comprises a longitudinallyY movable plunger 41 slidablymounted in a tubular guide 42 carried by aboss 43 cast integral with thehousing 1 and extending outward therefrom, as'shown. A union 44 isscrewed on the outer end of the boss 43 and clamps the guide member 42thereto. VAn oscillating handle 45 is supported by the union 44 and acoiled spring 46 in the union 44 normally maintains the outer end of theplunger 41 against the inner end of the handle 45 so that the plunger'will be moved inward b *thehandle in any direction that the handle maybe oscillated. A cup nut 47Y is screwed on the inner end ofk the tubularguide 42 against a packing 48for' preventing water leaking out of thevalve about the plung- At the inner end of the plunger 41 is a block 49locatedV in the slot 23 and carrying a depressible pin 50 normallyprojected above the block by a coiled spring 51 surrounding the pin in arecess provided in the block for the pin, asshown in Fig. 1. The

vlower end of the spring 51 seats against a nut 52 screwed into thelower end of the recess and through which nut the in moves so as to beguided by the nut. he upper end of the spring engages under a shoulderder or enlargement 53 on the pin so as to reject the pin above the blocklso that the pmvwill lstrike against the lower end ofthe lever 20 whenthe handle V45 is moved to openthe auxiliary valve 15. "The block 49 isprof 'is thereupon raised by the pressure on its under side to open thedischarge side of the device to the intake' side 3. As the main valve 6moves upward, the lever .20 is carried therewith out of contact with andabove the pin 50, whereupon the lever 20 i's'free and the spring 18closes the auxiliary valve 15 and swingsfthe lever 20 back into itsnormal valve-closing position. The pin 50 comes into contact with thelever 20 far enou h above its lower end to insure holding t e auxiliaryvalve 15 open for the greater portion or' the upward lmovement of themain valve 6, due to the 'fact that the lever does not trip offthe'upperend of the pin until* just before the mainvalve-G reaches thelimit of its upward movement. This necessitates substantiallyV the samedischarge of li uids from the chamber 7 in each operation o the valve,and as a result a predetermined flush is obtained' at all times, becausethe period of time for the refill of the chamber 7 to automaticallyclosey the vmain valve 6 is always the same.

In the closing movement of the main valve 6, the pin 50 will be in thepath of downward movement of the lever 20 should the handle 45 be stillheld in valve-opening position. Vith the pin 50 depressible, -the mainvalvevmay still close without unseating the auxiliary valve 15 becausethe lever 20 as it is brought into contact with `the upper y `end of thepin 50 will depress it and allow the lmain valve to close withoutunseating theauxiliary valve. (See Fig. 4.) When the handle45isreleased, the spring 46 will move the plunger 41 outward and carry thepin 5() from under the lowerv end of the lever 20, whereupon the spring51 will immediately project thefpin 50 upward so asf to return it toitsnormal positionl for again opening the auxiliary valve upon theoperation of the handle 45.

Vith this construction, it is apparent that the pin 50 will notinterfere withor lprevent the closing of the main valve in any positionof the pin 50 whether directl the vlever 20 therefrom. The slot-23 inthe cylind'rie'guideA @not unor completely re'eased Cil only permits thepin 50 to reach thelever varm 20, but also permits the lever to swing'without interference by the guide 9.A The vslot23 guides the block 49and thus maintains the pin 50 in proper alignment with the lower end ofthe lever 2O by preventing .turning of the block with respect totheplunger 4l. The slot 23 also permits the pin 59 to operate .through thecylindric guide 9 andvthus enables the height of the valve device to bematerially reduced by loeating the parts closer to the main Vvalve, 6thanY is possible when the parts are located beneath the lower end ofthe guide. This feature ,of reducing the height of the valve ldevicefis.also made possible by having the actuating mechanism for the auxiliaryvalve l5 operable between the ends of the guide 5,

which when disposed as in Fig. l is cored out on one side for Vthepurpose.

The upper ends Vof the webs l() of the .guide 9 terminate in an annularshoulder .55 against which the inner central portion ot the gasket l1 isclamped on screwing the guide intol the plate 6a. This maintains thegasket l1 tightly in the retainer l2 and prevents the gasket fromwarping or weaving through saturation, andi thus insures a perfeet seatfor the main valve 6 in its closingv movement.

, Briefly, the valve device operates as follows. On operating the handle45, the auX- iliary'V valve l5 is raised, relieving the .pres sure -`inchamber 7 so that the pressure on the intakevside of the valve will littthe main valve 6 off its seat and perm-it the flow to pass from intake 3to discharge 4 through guide cylinder between the same and the .guide 9.As soon as the lowerend ot' the lever 2O is lifted from the pin 50, thespring 18 will close the auxiliary valve 15, whereupon the pressure inchamber 7 is again built up through by-pass 2G, Vand main valve 6 willbe automatically closed. This returns the lever k20 to a posit-ionwhereby it may again be opened by actuating the handle 45.

The valve device shown and described is simple Vin its construction,positive and quick in operation, and silent at all times, and permits apredetermined discharge of Vwater under all pressures, regardless ofwhetheixthe handle 45 is held open or closed for the auxiliary valveoperable through the cylindric guide 9, the position of the operatingmechanism may be brought more or less in the plane of the intakeconnection 3, thereby avoiding an oversized and ungainly structure aswhen the intake connection and the handle operating structure are inwidely separated planes. y

The details of structure and arrangement of parts shown and describedmay be vari ously changed and modified without'departing :trom thespirit and scope ot our invention.
